deal's gap nklr

[biffy9lanky13]

I have just returned from a week touring Ireland on my Tengai. The first day consisted of a 220 miles motorway trip to the Liverpool ferry and a similar amount from Dublin to Galway. On arriving at Galway the headlight was very dim, even when revving up and it just started up (flat..ish battery) The next day it started ok and ran fine for the next 3 days, although I did buy a set of jump leads just in case. On the final day the bike only just started and I had to be jumped off in the petrol station on the motorway journey home. Well, the trip was great, but what's up with the bike?? When revving the bike the voltage on the white wire on the R/R stays constant at the same voltage as the battery. If the Brown / White wire is disconnected from the R/R the bike charges, The voltage goes up to 13+ v and the lights get brighter. If the wire is then reconnected the voltage on the white wire returns to 12v. The three wires from the Magneto all show 12v and if the white wire is disconnected the voltage on the terminal goes to over 30+ V There is a 1.2K ohm short to earth on the Brown /White terminal on the R/R. My question is is the R/R knackered The first day in Ireland was very warm and the heater fan was kicking in. My idea is that, the R/R stopped working because of the heat, damage was caused but it was not terminal, clearing up when the bike cooled overnight. And it gave up for good on the second to last day. Your comments would be much appreciated and if you ever get the chance to tour Ireland I can confirm that the Guinness is as good as they say and the roads are as bad. Thank a lot Rick

Bring your battery to a shop and have them check it. Or, if you have a battery charger, charge the battery for a few hours and then check the battery under load. Do this by reconnecting the battery. Then turn the key to the start position so the lights are on. Check the battery voltage, it should be 12VDC. If not, your battery is bad. Ed A15

Most of the time, a problem like the one you've described isn't the fault of the battery: it's corrosion where the cable lugs seat against the battery terminals. The battery and it's related circuit paths are low-tech and high maintenance. On an electric start only bike, time spent on the little things is well spent. I'm not talking about the white, powdery junk on the terminals; that's way past the corrosion problem. It's the grey color of the terminals, combined with the brown color of the cable lugs. It doesn't take much resistance to turn back 12 volts. Best to shine the terminals and lugs whenever you service the battery, and apply a little Vaseline or Molygraph grease to the point of contact at reassembly. That way, the battery will get something from the charging system. I cover this topic on my website. Jake You're welcome to visit my website at:

[...] Vaseline is conductive? Mister_T Melbourne Australia

No, you wouldn't want conductive grease. Shiny, unoxidised metal-to-metal contact is very conductive, and a non-conductive grease prevents electrolytic corrosion of the battery terminals and wire ends. It also keeps moisture and air away. Di-electric tune-up grease (has lots of silicone in it) is maybe even better. Devon A15 Ted Palmer wrote:

Ok, it's only a hundred amps or so.

Is that electrolytic corrosion or galvanic corrosion?

Metal-metal contact is nice, metal-dielectric-metal is better? If all you want is something that insulates and keeps moisture and air away, hit everything with spray paint before assembly. Mister_T Melbourne Australia

Every year we do. (hence Miata Myk)
